The foot member 2 isfprovided :it its lo Wer end with :i forwardlyinolined 'heel 16 whieh is. in turn. provided at either side thereofwith depending'eers 17--17 conf neeted hy n cross-member 1S. The upperedges of these. ears form shoulders 1S* upon The fiinotionxot this plate13 will the member 2 and, when the pieker-stick is in position upon theloom. they underlie the,

of the slot T and eti'ectivly prevent the picker-elink' from jumping outof said slot when thclfioui is in operation.

The picker-stiel: is provided with a. heel 'stre p :20 secured herein tothe lowerend of the member l sind :it the 'from' face thereof by asuitable. fastening: means. herein the holt. 5.- T he heel strap 20.Fig. extends downward. against the inclinedvfece 21 of the foot 2, andforward to f1 siiitahletension device, herein a roll 22, ctiiated by acon-r tained springiiot shown. '"his,tension roll is provided with u'suitablefmeang kherein the thumb-screw 23, for regulating the pull lier1S serves notr onlyr :is im additional means to prevent. the strap $20from jumping from its positionhetiveen the'eiirs 17-17, but. it :ilsoserve/sto assisty in bringing the picker-stick to il; position ot' restat the end of the lay. as will he explained.

T he picha-stick, Fia. 2. is adoptedA to he :actuated by the usual lugstrop 24. The lay is shown et ".5 partly broken wily.

In assembling. the member l of the pickerstir-l: first sented in inemherQ, the flanges I] -11 of theslmnl: l0 serving.Y to insure its eorreetvertical adjustment therewith. The Y holt. 5 is then inserted throughthe upright :mn 3 of the rocher 4, the shank 10 of the ineinher 2, themember I and. the heel strap 520 :ind is secured in position bye nutthewasher .27 being: positioned hetween said nut :ind seid ineinher ifdesired. After the pielieistirlc has heen correctly positioned theiosiioninf )lato l?. is nrliusted so that its' I .1: l

lower edge will rest. upon the. upper end of thil :irm 3 :inrl tho screw1'5 is turned up lo lock said member 13 securely in pesit-ion.

' roll 22 is now ad? If atV any time, however, it is necessary, m orderto replace the member 1 of thepiclterstick, or for any other reason toloosen or remove the bolt 5 and disconnect the two members l and 2, sucheen be done Wit-hout disturbing the existing adjustment of the memberv:Zwith respect to the member 3, the

positioning .plate 13A holding the member 2 A but convenient, byvarying` the adjustment 35, weather or otherwise to afford a more efcfthe lower heel member 2 with relation to the upper member 1 of thepicker-stick and with relation to the shoe' (3, asl above described, tovary the backward position at rest of the picker-stick, as may benecessa to kproperly cushion the shuttle in its bac o wardmovement. Thatis to say, bv raising;- the foot member 2 with respect to the roclter 4:the angularity of the heel strap for angiven tension-of spring. willbring the picker-Stick to rest at a point farther removed from the endof the slot in the lay than .would be the ease if said heel member wereadjusted to a lower position, and since the adjustable parts at alltimes are readily accessible andronvenicntly adjustable it is possibleto adjust the picker-sticks of a number of looms at any time tozsuitchanging` conditions of fective shuttle and spring;r actionwilhoutdanger of unduly pounding the parts. An-

gular adjustment of the picks-Slick with respect to the rocker 4 may behad by means of lthe set screw 28 and loeknnt 29. e

My improved picker-stick described hercin is more effectively controlledin its action above referred to .by means of the member 18 between theears 17, underlying the strap 20 and before referred to` When thepickersticl: moves forward the member l1S is thrown backward, away fromthe strap 2()l but when the picker-stick, in its return movement,approaches the end of the lay thc member 18 moving forward contacts withthe strap 2O at its under face, and. as the movement of the picker-stickcontinuesl this member 18 presses with increasing,r force against. saidstrap. `The pull of the roll 22 upon the strap 20, as it rcturnsthepiekerstiek, also tendsv to straighten said strap between the point.where it leaves the sur- -face of the roll 22 and the correspondingpoint upon the inclined surface 21 of the member 2 of the picker-stick,and when the return movement of the picker-stick has brought the. member18 in contact with the under side of the strap 20 the pressure of saidmember 18 against the under side of the strap tends tor offsetany'tendencyv ofthe ,i roll to return the picker-stick initially beyondthe position of rest of,tl 1e pieltcr-slick and` consequent-ly tends tobring the pickersticltto a position of rest. at'such time the 70 lateralpressure of the strap 20 is equal upon the face 21 of the member :2 andcross-member 1S, which is the normal position at rest. of thepicker-stick.

In order to prevent the picker-stick from jumping out of the `shoe 6,which it will often do if the pull of the tension roll 22 upon the heelStrap if() is not strong enough tolteep the pickensiiclt in. positionand unlesslhe pickersticlt is provided with means to keep 1t fromjumping, ithas often been necessary to increase theupull'of the tensionroll upon the heel stra p 20 beyond what` was necessary to simply returnthe picket* force against the end of thelay and to overcome the.consequent pir to the looni and to savonear and loosening of the picker`1t has stick to tbe end of the lay. Such action of -the roll returnsthe picker-stick with great been conunon to place a pad or bunt of 'noleather or other suitable material at the end of t-belay to act as acushion for the pickersiick in its rel urn movement. been customary tosecure a'sprinpr upon the lt. has also side ofthe slot in the lay insuch position that the picker-stickwill contact with itin the returnmovement and thus be stopped before itiealcbcs the end of the lay.`

` lly tbeuse ot' my improved form of piekerstickY it is possible t'o soaccurately adjust 163 the movement of the pickenstiek and the action ofthe roll 22 thereupon that th'e pickcivsticlt will be properly returnedto theend of the lay withoutundue force and the danger of its jumping'from its seat. This 105- cushionedstopping of the picker-stick abovedescribed reduces the inclination of the shut tlc to rebound from thepicker-stick, which rebound .causes breaking of the filling and ltinkingthereof and prevents the pickerl stick in its next oscillation fromimparting to the shuttle its proper forward movement. The vaboveadjustments accordingly eileet an adjustment o`f the tension upon theheel strap to regulate the movementofV the picker-stick under varyingconditions and permit. the movement referred to to be controlled at alltimes. l have ascertained that proper adjustment of tho pickel-stickrespecting the tension foil will remove the U0V danger of damage arisingfrom'the improper Contact of the Shuttle with the pickerstiel( andinsures proper movement of the'-y shuttle.' The use of my picker-stickalso obviates the necessity for using the pad or bunt now so commonlyused to stop the movement of the picker-stick in the lay; removes alldanger of the heel strap running off the hecl'of the piekerstiek; thedanger of the break-out from breaking of the heel strap is lessened andjumping of the piekerstick is obviateil.

Manythingsgimong them the condition of i the weather, which isconstantly changing, ,i

have adirect influence upon the movements of the various parte of theloom land neces- Sitate frequent a'd3ustnient thereof. My in- E ventioiipermits ready adjustment ot the nection therewith of the strap 2O in'rela- `tion to tbe fiilerinii of the picker-stick.
